New Rubber Goods in the Market. 



AN OIL-RESISTING RED TREAD TIRE. 



EVERYBODY knows that oil has a most deleterious effect 

 on rubber. That is a too well known fact to people who 

 have to use tires over oiled roads. In these days of auto- 

 niobiling a very considerable percentafie of the roads are oiled. 



About a year 

 ago the Penn- 

 sylvania Rub- 

 ber Co., pro- 

 duced a vacuum 

 • up tread tire 

 cjf the ordinary 

 gray rubber 

 color. These 

 vacuum - cups 

 were intended 

 to make the 

 tire non-skid- 

 ding, on the 

 principle that 

 when these 

 cups were com- 

 pressed against 

 the surface of 



The Red Tre.xd Vacuum-Cup Bicycle Tire, 'he road a cer- 

 tain suction 



was produced that kept the tire from slipping sidewise. This 

 ■company has now brought out another vacuum-cup tread tire, 

 but instead of making it of gray rubber the tread is made of red 

 rubber. The ingredient in the composition which gives the red 

 color was put there, not primarily for that purpose, but in order 

 to resist the action of oil, and to the extent that this new com- 

 position is oil-resisting it of course increases the durability and 

 satisfactory service of the tire. [Pennsylvania Rubber Co., 

 Jeannette, Pennsylvania.] 



WATERPROOF TIRE TRUNKS. 



In these days of extensive motoring when almost everyone 

 who owns a ear converts it at times into a touring car and goes 

 on long trips from one city to another, every available inch 

 of space in the car that can be used for baggage has to be 

 utilized. With this idea in mind, certain manufacturers have 

 put out circular packing cases to fit into the extra tires that have 

 to be carried on any considerable journey. 



RoLL-DooR Tire Trunks. 



The accompanying cuts show two styles of the "Roll-Door Tire 

 Trunk," made for this purpose. It is light and thin, but strong 

 and thoroughly waterproof, being made of three-ply wood veneer, 

 covered with a waterproof duck, bound with leather. The 

 rioor is constructed with a catch lock, so that it rolls back at a 

 touch. It is an exceedingly serviceable motor trunk. [Nathan 

 Novelty Manufacturing Co., 84 Reade street, New York.] 



Rubber Baseb.\ll Curver. 



A BASE-BALL CURVE PRODUCER. 



For the last 25 years every healthy, red-blooded, patriotic 

 American boy has had just one ambition — to pitch a curved ball. 

 Some have been able to attain to this ambition after more or 

 less painstaking efl'ort, and some have not. But all can take 



heart now, for here is a 

 device for assisting the 

 fingers of the pitcher's 

 hand to give the ball a 

 curve. It is quite a sim- 

 ple device, consisting of 

 a rubber band, about an 

 inch wide, which goes 

 over two fingers of the 

 hand. Attached to this 

 band, on the side that 

 comes next to the ball, 

 is a rubber vacuum cup. 

 The theory is that when 

 the ball leaves tiic hand, the vacuum cup clings for an instant 

 to the l)a11 and gives it a decided twist as it starts on its way 

 for tlie home plate. Just whether "Christy" Matthewson and 

 "Rube" Marquard will find this appliance of any material assist- 

 ance cannot at present be definitely stated; but without question 

 it will appeal to a great many thousand boys who, during the 

 summer months, will spend all their afternoons on the village 

 diamond. [Patentee, Ralph Wilson Jones, Lincoln, Nebraska.] 



VACUUM BASKET-BALL SOLES. 



Rubber molded goods of the vacuum-cup description have been 

 made for some time, particularly in the line of toilet brushes and 

 horse brushes. More recently soles for shoes to be used in ath- 

 letics have 

 been made of 

 this pattern ; 

 and now 

 comes a sole 

 p a r t i c u- 

 larly designed 

 for the basket 

 ball player. 

 It is made by 

 the same 

 company that 

 has been put- 

 ting out the 

 vacuum - cup 

 brush and 

 other molded 

 goods men- 

 tioned above. 

 The game of 

 basket ball is 

 p a r t i c u- 

 larly hard on 

 t h e player's 

 feet, as it is 

 an indoor 

 sport and usually played on hard floors. This suction-cup sole 

 is designed to give the player the maximum comfort and im- 

 munity from sliding. When in his wild dives and rushes across 

 the floor he lands on the soles of his feet, he strikes on the edges 

 of the raised cups which are immediately flattened, so that the
